Can Machines Think Like Humans? A Behavioral Evaluation of LLM Agents in Dictator Games

MalRAG is a novel retrieval-augmented framework designed for the fine-grained identification of open-set malicious traffic in cybersecurity. As cyber threats continuously evolve, the ability to detect both known and new types of malicious traffic is paramount. This framework utilizes a frozen large language model (LLM) to construct a comprehensive traffic knowledge database, employing adaptive retrieval and prompt engineering techniques to enhance identification capabilities.

SpiderGen is a new workflow that utilizes large language models (LLMs) to enhance the process of conducting Life Cycle Assessments (LCAs) for consumer products. These assessments are crucial for understanding the environmental impact of goods, particularly in the context of greenhouse gas (GHG) emissions. SpiderGen integrates traditional LCA methodologies with the advanced reasoning capabilities of LLMs to produce graphical representations known as Product Category Rules Process Flow Graphs (PCR PFGs). The effectiveness of SpiderGen was evaluated against 65 real-world LCA documents.

A new framework for detecting errors in SQL generated by large language models (LLMs) has been introduced, focusing on estimating uncertainty at the node level within the query's abstract syntax tree (AST). The method employs a semantically aware labeling algorithm to assess node correctness and utilizes a classifier to predict error probabilities for each node. This approach allows for precise diagnostics, significantly improving error detection compared to traditional token log-probabilities across various databases and datasets.

The article discusses the challenges and potential of scaling prompt optimization using LLM-provided textual gradients. While this method has proven effective for automatic prompt engineering, issues arise when increasing training data due to context-length limits and diminishing returns from long-context degradation. The authors propose a new approach called Textual Stochastic Gradient Descent with Momentum (TSGD-M), which utilizes momentum sampling to enhance training stability and scalability.

Log anomaly detection is essential for identifying system failures and preventing security breaches by recognizing irregular patterns in large volumes of log data. Traditional methods depend on training deep learning models with clean log sequences, which are often difficult and costly to obtain due to the need for human labeling. Existing automatic cleaning methods do not adequately consider the specific characteristics of logs. The proposed LogPurge framework offers a cost-effective solution by using a rule-enhanced purification process that selects normal log sequences from contaminated dat…

ReflexGrad is a new architecture designed to enhance zero-shot generalization in large language model (LLM) agents. It integrates three mechanisms: hierarchical TODO decomposition for strategic planning, history-aware causal reflection for identifying failure causes, and gradient-based optimization for systematic improvement. This approach allows agents to learn from experiences without needing task-specific training, marking a significant advancement in reinforcement learning and decision-making.

OG-VLA is a new architecture that integrates Vision Language Action models with 3D-aware policies to enhance robot manipulation tasks. It addresses the challenge of translating natural language instructions and RGBD observations into robot actions. While 3D-aware policies excel in precise tasks, they often struggle with generalization to new scenarios. Conversely, VLAs are adept at generalizing across instructions but can be sensitive to variations in camera and robot poses. OG-VLA aims to improve this generalization by leveraging knowledge from language and vision models.

Large Language Models (LLMs) have shown remarkable capabilities in generalizing across various domains and modalities. This study explores their potential to encode astrophysical information typically derived from scientific measurements. The research focuses on two primary questions: the impact of prompting on the codification of physical quantities by LLMs and the linguistic aspects crucial for encoding the physics represented by these measurements. Sparse autoencoders are utilized to extract interpretable features from the text.
